The use of a structural free iliac crest autograft for the treatment of acetabular fractures.

Introduction: Bone and cartilage deficits in the posterior acetabular wall are severe complications resulting from the unsuccessful management or delayed treatment of acetabular fracture. This potentially disastrous condition cannot be treated reliably with the use of reconstruction plates and screws alone. Therefore, this technical report describes a modified anatomical reconstruction method that uses a structural iliac crest autograft and an acetabular tridimensional memory alloy fixation system (ATMFS) to treat late-stage deficits in the posterior wall of the acetabulum.

[Management of weight-bearing area fracture of acetabulum].

Acetabulum, as the important factor for weight bearing of the upper body, has its unique anatomic features and complicated physiological function. The integrity and stability of the lunata articular surface in the dome region of acetabulum, is the important base to bear the physiological function of acetabulum. The fracture related to this part will cause relation change of contact area and stress between head of femur and acetabulum.
